To like and dislike the same things, this is what makes a solid friendship.

One of the most beautiful qualities of true friendship is to understand and to be understood.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

That friendship will not continue to the end which is begun for an end.

Laughter is not at all a bad beginning for a friendship, and it is far the best ending for one.

Am I not destroying my enemies when I make friends of them?

A man cannot be said to succeed in this life who does not satisfy one friend.

Each friend represents a world in us, a world not born until they arrive, and it is only by this meeting that a new world is born.

A man's friendships are one of the best measures of his worth.

Since there is nothing so well worth having as friends, never lose a chance to make them.
